Clarifier - Wikipedia
Clarifiers are settling tanks built with mechanical means for continuous removal of solids being deposited by sedimentation. A clarifier is generally used to remove solid particulates or suspended solids from liquid for clarification and/or thickening. Inside the clarifier, solid contaminants will settle down to the bottom of the tank where it is collected by a scraper mechanism. Concentrated impuri…

- General Information
Thickeners and clarifiers use slowly rotating rake arms to separate solid particulate. A liquid feed with suspended solids is fed into a tank with a diameter of 5 to 500 feet. As the particles settle, angled rake arms move the concentrated slurry toward the center of the tank, where it is remov… - Equipment Design
There are three main types of thickeners/clarifiers: bridge support, column support, and traction. In a bridge support thickener, such as the one shown below, the rakes and drive mechanism are suspended from a bridge that spans the diameter of the tank. They are usually only economical …
